some question about housing. (Singapore)

upcoming week I will move to Singapore from Malaysia and I am gonna stay at least 2 years there, so I need to rent a room.

My work place will be in beach road Protected content

so my question first is which one is more convenient? bus or MRT? I looked into ibilik.sg but it looks like very messy, without pictures ( in Malaysia it's most reliable one, but for singapore look like is not that much popular).I also looked into nestia.com but it looks over priced since most of the house is advertised by agents.

which site you are suggesting to look for room? and which area?

I welcome to any information that you may think is useful for me to know
